Ford returned to work this week after a two-month stay in rehab for drugs and alcohol. The mayor of Canada's largest city said he's used cocaine, marijuana and hallucinogenic mushrooms, but not heroin. He acknowledged he smoked crack but denied he was a crack addict.

"You name it, I've abused it," he said.

Ford refused to say whether he'd resign if he falls of the wagon again. Asked if that was good enough for the people of Toronto, Ford said it would be up to them to decide in the Oct. 27 election.

"I'm taking one day at a time. I did not drink yesterday, I haven't drunk today," Ford said.

Ford made the remarks in interviews with the Canadian Broadcasting Corp. and CP24. He returned to City Hall earlier this week and gave a statement but refused to take questions.

Ford acknowledged last year that he had smoked crack in a "drunken stupor." His reign as mayor has been marred by revelations about his drinking problems and illegal drug use. He has been repeatedly videotaped and photographed while intoxicated and has made racist and homophobic remarks on tape.

Ford has not abandoned his effort to seek a second term in October. He said he won't be resigning to deal with his substance abuse issues.

"I love my job and keeping busy is the best thing for me," he said.

He said he's been abusing drugs and alcohol for years and said his job is not what drove him to abuse substances.
